Iterium and Postal got the fist four bosses down in their first raiding night. Many other guilds (approx 750 of the most hardcore) also seem to have problems on the 5th boss, Elegon.
These are the ones I am reading up on these days (cant really watch videos as I am at work):
The Stone Guard (http://icy-veins.com/the-stone-guard-detailed-strategy-wow)
Feng the Accursed (http://icy-veins.com/feng-the-accursed-detailed-strategy-wow)
Gara'jal the Spiritbinder (http://icy-veins.com/gara-jal-the-spiritbinder-detailed-strategy-wow)
The Spirit Kings (http://icy-veins.com/the-spirit-kings-detailed-strategy-wow)
Please remember that some videos are from early beta and might be outdated! Youtube posts will clearly show this :-)

For this quest you need to do one of the scenarios (just a room with 4 or 5 bosses) & get a nice 450 weapon :)
